UPDATE: The California Department of Food and Agriculture (CDFA) is hosting a public meeting to present information and answer any questions regarding the citrus greening disease treatment area. The public meeting is tomorrow, Wednesday, August 16, 2017, from 5:30 p.m. to 7:00 p.m., at the Anaheim Central Library, Meeting Rooms 1 and 2, located at 500 W. Broadway in Anaheim.

On July 21, 2017, the California Department of Food and Agriculture (CDFA) confirmed the presence of the causative bacterial agent of the citrus disease huanglongbing (HLB) from insect vectors collected in the city of Anaheim, Orange County. HLB is a devastating disease of citrus worldwide and is spread through feeding action by populations of the Asian citrus psyllid (ACP), Diaphorina citri Kuwayama. In order to determine the extent of the infestation, and to define an appropriate response area, additional survey took place for several days over a one-square mile area, centered on the detection site. The results of this additional survey indicated that the infestation is sufficiently localized to be amenable for effective implementation of the California Department of Food and Agriculture's (CDFA) current ACP and HLB response strategies, which include treatment for ACP.
A Program Environmental Impact Report (PEIR) has been certified which analyzes the ACP and HLB treatment program in accordance with Public Resources Code, Sections 21000 et seq. The PEIR is available online. The treatment activities described below are consistent with the PEIR.
In accordance with integrated pest management principles, the CDFA has evaluated possible treatment methods and determined that there are no cultural or biological control methods available to control ACP in this area.
The treatment plan for the ACP infestation will be implemented within a 400 to 800-meter radius of each detection site, as follows:
- Temp SC Ultra (cyfluthrin), a contact insecticide for controlling the adults and nymphs of ACP, will be applied from the ground using hydraulic spray equipment to the foliage of host plants; and
- Merit 2F or CoreTect (imidacloprid), a systemic insecticide for controlling the immature life stages of ACP, will be applied to the soil underneath host plants. Merit 2F is applied from the ground using hydraulic spray equipment, whereas CoreTect, if used in place of Merit 2F, is applied by inserting the tablets into the ground and watering the soil beneath the host plants.
Residents of affected properties may be invited to a public meeting where officials from CDFA, the Department of Pesticide Regulation, the Office of Environmental Health Hazard Assessment, and the county agricultural commissioner's office will be available to address residents' questions and concerns. Residents are notified in writing at least 48 hours in advance of any treatment in accordance with the Food and Agricultural Code, Section 5779 and 5401-5404. Following the treatment, completion notices are left with the residents detailing precautions to take and post-harvest intervals applicable to the citrus fruit on the property. Treatment information is posted online at the California Department of Food and Agriculture's website.
Press releases, if issued, are prepared by the CDFA information officer and the county agricultural commissioner, in close coordination with the program leader responsible for treatment. Either the county agricultural commissioner or the public information officer serves as the primary contact to the media.
For any questions related to this program, please contact the CDFA toll-free telephone number at 800-491-1899 for assistance. This telephone number is also listed on all treatment notices.
